Cov yeeb nkab fittings txhaj tshuaj molding feem ntau ntsib qhov xwm txheej uas pwm tsis tuaj yeem sau thaum lub sijhawm ua tiav. Thaum lub tshuab txhaj tshuaj molding nyuam qhuav pib ua haujlwm, vim tias qhov kub ntawm pwm qis dhau, qhov cua sov poob ntawm cov khoom siv PVC molten loj heev, uas yooj yim rau kev khov thaum ntxov, thiab qhov tsis kam ntawm qhov pwm qhov loj heev, thiab cov khoom tsis tuaj yeem sau qhov khoob. Qhov xwm txheej no yog qhov ib txwm thiab ib ntus. Nws yuav ploj mus tom qab txhaj tshuaj tas li ntawm cov pwm digital. Yog tias pwm tsis tuaj yeem sau txhua lub sijhawm, xav txog cov xwm txheej hauv qab no thiab ua qhov kev hloov kho kom tsim nyog:

Cov npuas dej ntawm cov yeeb nkab

Cov npuas cua sov raug tsim los ntawm qhov kub siab. Qhov kub ntawm cov txheej txheem siab dhau yuav ua rau muaj cov npuas hauv cov khoom siv volatiles hauv cov khoom siv raw, thiab tseem yuav ua rau cov khoom lwj ib nrab.PVCcov khoom siv los tsim cov npuas, uas feem ntau hu ua cov npuas kub. Kho qhov ceev ntawm kev txhaj tshuaj kom raug

Qhov kev txhaj tshuaj ceev dhau lawm. Vim tias cov txheej txheem molding ntawmPVC-UCov khoom txhaj tshuaj pwm yuav tsum siv qhov ceev txhaj tshuaj qis dua thiab qhov siab txhaj tshuaj siab dua. Qhov ceev txhaj tshuaj tuaj yeem hloov kho kom haum.

Yog tias lub rooj vag me dhau los yog qhov seem ntawm txoj kab ntws me dhau, qhov tsis kam ntawm cov khoom ntws loj dhau. Lub rooj vag thiab qhov seem ntawm tus khiav tuaj yeem ua kom loj dua kom txo qhov tsis kam ntawm cov dej yaj.

Cov dej noo lossis lwm yam khoom uas tsis muaj zog hauv cov khoom siv raw yog siab dhau lossis cov khoom siv raw tau khaws cia ntev dhau, thiab cov dej noo hauv huab cua raug nqus. Tswj cov ntsiab lus ntawm cov khoom siv raw thaum yuav cov khoom siv raw, thiab cov khoom siv raw thiab cov khoom pabcuam yuav tsum tsis txhob khaws cia ntev dhau thaum lub sijhawm lossis thaj chaw uas muaj dej noo ntau hauv huab cua.

Cov khoom tsis zoo gloss

Qhov ci ntsa iab ntawm cov khoom txhaj tshuaj PVC feem ntau yog cuam tshuam nrog qhov fluidity ntawm cov ntaub ntawv PVC. Yog li ntawd, kev txhim kho qhov fluidity ntawm cov ntaub ntawv yog ib qho tseem ceeb los txhim kho cov khoom. Vim tias qhov kub ntawm cov khoom molten qis thiab qhov fluidity ntawm cov ntaub ntawv tsis zoo, qhov kub ntawm cov khoom tuaj yeem nce ntxiv kom haum, tshwj xeeb tshaj yog qhov kub ntawm lub nozzle.

Cov mis tsis tsim nyog, yog li ntawd cov yas ntawm cov khoom tsis nyob hauv qhov chaw lossis cov khoom sau ntau dhau, cov mis yuav tsum tau kho, thiab cov yas zoo thiab cov dej ntws ntawm cov khoom yuav tsum tau txhim kho los ntawm kev sib xyaw ua ke ntawm cov khoom pab ua tiav, thiab cov nyiaj ntawm cov khoom sau yuav tsum tau tswj.

Tsis txias txaus rau pwm, ua kom pwm txias zoo dua. Yog tias qhov loj ntawm lub rooj vag me dhau lossis qhov hla ntawm tus khiav me dhau, qhov tsis kam loj dhau. Koj tuaj yeem nce qhov hla ntawm tus khiav kom haum, nce lub rooj vag, thiab txo qhov tsis kam.

Cov dej noo lossis lwm yam khoom uas yaj tau hauv cov khoom siv raw ntau dhau. Cov khoom siv raw tuaj yeem qhuav tag, lossis cov dej noo lossis cov khoom uas yaj tau tuaj yeem tshem tawm los ntawm cov khoom siv. Yog tias cov pa tawm tsis zoo, tuaj yeem ntxiv ib qho qhov tso pa tawm lossis qhov chaw ntawm lub rooj vag tuaj yeem hloov pauv.

Muaj cov kab vuam uas pom tseeb

Qhov kub ntawm cov khoom yaj qis, thiab qhov kub ntawm lub thoob tuaj yeem nce ntxiv kom haum, tshwj xeeb tshaj yog qhov kub ntawm lub nozzle yuav tsum nce ntxiv. Yog tias qhov siab txhaj tshuaj lossis qhov ceev txhaj tshuaj qis, qhov siab txhaj tshuaj lossis qhov ceev txhaj tshuaj tuaj yeem nce ntxiv kom haum.

Yog tias qhov kub ntawm pwm qis, qhov kub ntawm pwm tuaj yeem nce ntxiv kom haum. Yog tias lub rooj vag me dhau lossis qhov seem ntawm tus khiav me dhau, koj tuaj yeem nce tus khiav lossis nthuav lub rooj vag kom haum.

Cov pa tawm pwm tsis zoo, txhim kho kev ua haujlwm ntawm cov pa tawm pwm, ntxiv cov qhov tso pa tawm. Lub qhov dej txias me dhau, yog li lub qhov dej txias tuaj yeem nce ntxiv kom haum.

Cov roj nplua nyeem thiab cov stabilizer hauv cov mis no ntau dhau lawm, thiab lawv cov nqi tuaj yeem hloov kho tau. Qhov chaw teeb tsa tsis tsim nyog thiab nws qhov layout tuaj yeem hloov kho tau.

Cov cim qhia txog kev poob dej hnyav

Gaoan lub siab txhaj tshuaj qis, yog li lub siab txhaj tshuaj tuaj yeem nce ntxiv kom haum. Lub sijhawm tuav lub siab teem tseg tsis txaus, koj tuaj yeem nce lub sijhawm tuav lub siab kom haum.

Lub sijhawm txias uas teem tseg tsis txaus, koj tuaj yeem nce lub sijhawm txias kom haum. Yog tias cov sol tsis txaus, nce cov sol kom haum.

Qhov kev thauj dej ntawm cov pwm tsis sib npaug, thiab lub voj voog txias tuaj yeem hloov kho kom txhua qhov ntawm cov pwm txias sib npaug. Qhov loj me ntawm lub pwm qhov rooj kaw lus me dhau, thiab lub rooj vag tuaj yeem nthuav dav lossis qhov loj, ceg, thiab tus khiav hla qhov ntev tuaj yeem nthuav dav.

Nyuaj rau rhuav tshem

Qhov nyuaj ntawm kev rhuav pwm yog los ntawm pwm thiab cov txheej txheem tsis raug, tab sis feem ntau nws yog los ntawm lub tshuab rhuav pwm tsis raug ntawm pwm. Muaj lub tshuab txuas khoom siv hauv lub tshuab rhuav pwm, uas yog lub luag haujlwm rau kev txuas cov khoom txias ntawm lub ntsiab, tus khiav thiab lub rooj vag: lub tshuab ejection siv lub pas nrig ejector lossis lub phaj saum toj kawg nkaus los tshem tawm cov khoom ntawm lub pwm txav tau. Yog tias lub kaum sab xis rhuav pwm tsis txaus, kev rhuav pwm yuav nyuaj. Yuav tsum muaj lub siab pneumatic txaus thaum lub sijhawm rhuav pwm thiab rhuav pwm. , Txwv tsis pub yuav muaj teeb meem hauv kev rhuav pwm. Tsis tas li ntawd, lub cuab yeej rub lub hauv paus ntawm qhov chaw faib, lub cuab yeej rub lub hauv paus xov, thiab lwm yam yog txhua qhov tseem ceeb hauv cov qauv rhuav pwm, thiab kev tsim tsis raug yuav ua rau muaj teeb meem ntawm kev rhuav pwm. Yog li ntawd, hauv kev tsim pwm, lub tshuab rhuav pwm kuj yog ib feem uas yuav tsum tau them sai sai rau. Hauv kev tswj cov txheej txheem, kub dhau, pub ntau dhau, siab txhaj tshuaj ntau dhau, thiab lub sijhawm txias ntev dhau yuav ua rau muaj teeb meem rhuav pwm.

Hauv kev xaus, ntau yam teeb meem zoo yuav tshwm sim hauv kev ua cov txheej txheem ntawmPVC-Ucov khoom txhaj tshuaj pwm, tab sis cov laj thawj rau cov teeb meem no yog nyob rau hauv cov khoom siv, pwm, cov mis, thiab cov txheej txheem. Tsuav yog muaj cov khoom siv thiab pwm tiav, cov mis thiab cov txheej txheem tsim nyog, cov teeb meem tuaj yeem zam tau. Tab sis hauv kev tsim khoom tiag tiag, cov teeb meem no feem ntau tshwm sim, lossis tshwm sim yam tsis paub cov laj thawj thiab cov kev daws teeb meem, nyob ntawm kev sib sau ua ke ntawm kev paub dhau los. Kev paub dhau los ua haujlwm nplua nuj kuj yog ib qho ntawm cov xwm txheej kom ntseeg tau tias cov khoom zoo meej.
